Aerating is the process of systematically puncturing the top layer of soil in a lawn and allowing the infiltration of water, oxygen and nutrients to the roots of the grass. After about two months, the soil also softens up alleviating the issue of constriction on the existing root system. Aerating is not a mandatory practice but is beneficial. Power Seeding is the process of slicing into the top layer of the lawn and inserting grass seed. This reduces lost seed and allows better germination rates for the seed. Power seeding is a practical and affordable means of installing a lawn or replacing larger damaged spots of a yard. Thatching is an important aspect of lawn care. Thatching is removing the dead and old grass from the lawn system. This allows new grass to grow and removes the unattractive brown and yellow grass from the lawn.
